Im looking to start a 2 seater budget off road build and have no idea what kind of battery or charging system I sound use.
I'd like to build 2 racks with 4 18v lithium 4ah drill batteries in series and have both of those in parallel to each other to double the amp hours (not sure how realistic that is) mainly for ease of charging and servicing.
Is this a fever dream or another way to accomplish the same idea. Totally new to Ev builds.
I'd like to have something that gives me Atleast an hour of play on a 72v 3000w motor it the bush. Here's the motor I was thinking of using

Also would like to be able to have something that I could have a back up battery or batteries on hand in case I need to quickly swap it out.
